Halfway Between 27 and 54

When you ask "What number is halfway between 27 and 54?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=27 and Y=54.

Halfway Between Line

To find the number halfway between 27 and 54, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 54 into our formula, we get:

(27 + 54)/2 = 40.5

Thus, the number halfway between 27 and 54 is 40.5.

To check that our answer is correct, we subtract 27 from 40.5 and subtract 40.5 from 54 and compare the two numbers:

40.5 - 27 = 13.5
54 - 40.5 = 13.5

As you can see, the halfway number is 13.5 higher than 27 and 13.5 lower than 54. Therefore, our halfway between answer of 40.5 above is correct.
